Special cutting materials such as nutrient soil, river sand and peat soil can be used. It is recommended to use the cutting medium which has been prepared and has been detoxified for family cutting, and medium and coarse river sand can also be used.
The substrate should be rinsed with clear water several times before use. Sea sand and river sand in saline and alkaline areas should not be used because they are not suitable for the growth of flowers and plants.
The selection of cutting branches is usually combined with the work of heart picking. The thick and pest free top shoots are taken as cuttings, and the top shoots are directly used for cutting.
The most suitable temperature for cuttings rooting is 18 ℃ - 25 ℃. If the temperature is lower than 18 ℃, cuttings rooting is difficult and slow. If the temperature is higher than 25 ℃, cuttings are easy to be infected by pathogens and rot. the higher the temperature, the greater the proportion of rot.
When cutting at low temperature, the main measure of heat preservation is to wrap the flower pot or container that is used for cuttings. If the temperature is too high, we need to shade the shading, cover 50% to 80% of the sunshine, and give the spray 3 to 5 times a day.
After cutting, the relative humidity of air must be kept at 75% - 85%. Spraying can increase humidity by 1 days to 3 times per day. The higher the temperature is, the more the number of sprays will be. The lower the temperature is, the less the time will be.
Cuttage Propagation can not be separated from sunlight, but the stronger the light, the higher the temperature in the cuttings, the more vigorous the transpiration of cuttings, and the more water consumption, which is not conducive to the survival of cuttings.
Therefore, 50% - 80% of the sunlight must be covered after cutting. After the root system grows, the shading net shall be removed gradually. It shall be removed at 4:00 p.m. every day in sunny days, and the shading net shall be covered before 9:00 a.m. the next day.
